World-renowned survivalist Bear Grylls ("Man vs. Wild," "Born Survivor") leads a non-stop extreme survival journey that tests 10 teams of two beyond their wildest imaginations as they venture into the unforgiving and dramatic landscape of New Zealand's South Island. Their mission is threefold: survive the wild, journey as a group and avoid elimination. Each week, Bear will send home one team. In the end, only one duo will remain - the team that he believes has shown the most heart, courage, initiative and resolve in their quest to "get out alive" and claim a life-changing grand prize of $500,000.
